Ok I misread your post at first. I would expect exactly as you, they would copy fcp euro model of buy replacement, send in broken part and get refunded once the broken part gets there.

What if you send the broken part first to get credit and use credit for replacement?

The situation you described is not a good policy just ending up with store credit not really replacement of the "warranteed" item.
